An ice cream server fills a cone, which is 15.7 cm high and 7.2 cm across, with ice cream. She then tops the cone with a nicely rounded half-scoop. On top of this she puts the second scoop. To the nearest cubic centimeter, how much ice cream did you receive?

The way I interpret the question:
The first scoop on the top is a half scoop, the second scoop is a full scoop ?
If the second scoop is also a half-scoop, then change the 3/2 to 1
you would have the volume of the cone + (3/2) spheres
